BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing the operation principle of the burglar alarm device of the present invention, and Fig. 2 is a partially enlarged schematic view showing the burglar alarm device shown in Fig. 1.

As shown in Figures 1 and 2, the burglar alarm device of the present invention includes a main unit 1 and a connector 2 and an alarm line 3, which is usually fixed to a fixed object that is difficult to be moved, such as a table top. The connector 2 is fixedly attached to the electronic device S to be protected when in use. The electronic device S is, for example, a mobile phone, a portable computer, a tablet computer, an electronic paper book, a digital camera, etc., which usually has a rechargeable battery that can be charged through an external charging line. The alarm line 3 is used to connect the host 1 and the connector 2.

As shown in Fig. 1, the main unit 1 includes a main control unit 101, a charging contact unit 102, and an internal connection 103. The charging contact unit 102 is connected to the main control unit 101 via an internal connection line 103 located inside the main unit 1. The connector 2 includes a charging terminal 202, a charging wire 203, and an alarm wiring 204. The charging terminal 202 and the charging line 203 are electrically connected. A charging line 203 is used to connect the charging port of the protected electronic device S. The alarm connection line 204 is used to connect the alarm line 3 to the protected electronic device S. The alarm line 3 is used to connect the alarm connection line to the main control unit 101 of the host 1.

The alarm cable 204 is connected to the electronic device S via a connector such as Micro USB, Mini USB, Lightning or the like. The charging line 203, the internal connection line 103, the alarm connection line 204, and the alarm line 3 are both double lines. Although the charging line 203 and the alarm connection line 204 are shown as two lines in FIGS. 1 and 2, in reality, the internal connection line 103 and the alarm line 3 are also two lines).

Thus, an alarm circuit is formed between the master device 101, the alarm line 3, the alarm connection line 204, and the protected electronic device S.

Also, the main body 1 and the connecting member 2 can be mechanically connected, and the positions of the charging contact 102 on the main body 1 and the charging terminal 202 of the connecting member 2 correspond to each other, so that when the main body 1 and the connecting member 2 are mechanically connected, they can be formed. Electrical contact. Thus, when the charging contact 102 and the charging terminal 202 are in contact, a charging circuit is formed between the main control device 101, the internal connection line 103, the charging contact 102, the charging terminal 202, the charging line 203, and the protected electronic device S. .

The master device 101 of the present invention has a power management module (see Fig. 3) that is capable of managing the supply of internal or external power sources through which the protected electronic device S is charged. On the other hand, the main control device 101 further includes an alarm detecting module (see Fig. 3) for receiving a signal from the alarm line 3 to detect whether the alarm circuit has an abnormality.

It can be seen that in the present invention, the charging circuit is connected to the main control unit 101 through the internal connecting line 103 of the main unit 1, and the alarm circuit is connected to the main control unit 101 via the alarm line 3. Thus, the length of the alarm line 3 can be set to a length required to allow a person to operate the electronic device S to be protected, and can have a length of several meters. Thus, the integration of the alarm line 3 and the charging line in one cable is avoided, and the charging line is unnecessarily long, so that the charging efficiency can be improved. The invention sets the charging circuit and the alarm circuit independently of each other, so that the wiring length of the charging circuit is minimized, the line loss is greatly reduced, the charging efficiency is improved, and the charging time is reduced.

The main control unit 101 shown in Fig. 1 is connected to an external power source through a main power line 4, but the present invention is not limited thereto, and the host unit 1 may also employ an internal power source.
